Question 1: Create the subsequent C++ functions and 'call' them each from main():
Part 1: Create a void function that takes as parameters two integers, adds them, and prints them out to the command line.
Part 2: Create a function that takes as parameters two doubles, adds them, and returns the result to the function that called it. Output the result from main().
Part 3: Create a function that returns the magic number 12 every time it is called. It has no parameters. Call it from main and output the magic number.
Part 4: Create a function that takes as a parameter a string name, and prints out that name to the command line. Call your function from main.
